摘要:
The present invention relates to new inclusion complexes of 2-chloro ethyl phosphonic acid formed with .alpha.-, .beta.- and/or .gamma.-cyclodextrin or a mixture thereof.The new inclusion complexes contain preferably 10-30% of 2-chloro ethyl phosphonic acid.The new complexes of the present invention are prepared by reacting 2-chloro ethyl phosphonic acid with .alpha.-, .beta.- and/or .gamma.-cyclodextrin or a mixture of one or more of the said cyclodextrins and linear dextrins and/or partially decomposed starch.The new inclusion complexes of the present invention can be used for the preparation of plant growth regulating compositions.
摘要:
The invention relates to fungicidal plant protecting composition comprising 3-90% by weight of a fungicidal active ingredient in admixture with 1-90% by weight of cyclodextrin and optionally with usual auxiliary agents.The advantage of the synergistic composition of the present invention is that identical fungicidal effect can be achieved with a significantly lower active ingredient dosage and this decreases the costs involved with the active ingredient and reduces the risks of environmental pollution as well.
